Packet transmissions generally require a transciver (or just resceiver if skipping sending), a computer, a Terminal Node Controller (TNC) for converting to/from serial for the computer and analog for the transciever. More recently software and faster computers have made it possible to replace the TNC with an adequate sound card and the right software, saving on the cost/bulk of the TNC and associated cabling. Software TNC running on a Raspberry Pi appears to be a good fit.
